Fine-scale population genetic structure of arctic foxes (Vulpes lagopus) in the High Arctic
Abstract Objective The arctic fox (Vulpes lagopus) is a circumpolar species inhabiting all accessible Arctic tundra habitats. The species forms a panmictic population over areas connected by sea ice, but recently, kin clustering and population differentiation were detected even in regions where sea...
